eprint-mon mea voctober 24, 1924.' semi no. 745cm 'Ihis- 'invention relates to apparatus for purifying the air ,in railway cars, houses, and other structures by preventing 'the en-v trance of' cinders, dust, insects and other.

such harmful substances or objects, and by introducing pure air thereto and'discharglli ing impure air therefrom.

Accor-dino' to my invention the Windows,

doors,` br other openings in a oar, house, or

other structure are provided with novel de vices whereby' jets or sheets of airpare dis-A charged outwardly from the openings' in such manner as to provide curtains or yshields which prevent the entrance of for eign matter and which at the same time' cause foul air to be Withdrawn from thev lstructure to give place to pure ai'r.

Provision may also be made for introducing pure air to the interior of the structure andsuch air may belcooled in such manner as to afford a comfortable temperature.

In carrying out my invention .in the way vnow best known to me, I pro vide a.-sou1ce-Y of compressed air which 1s. plpe connected with the devices for discharging air at the Windows, doors or other-o enmgs and which is also pipe connected wit ,devices for sup- 4 plying air to the interior of the structure.

Means is provided whereby` the air discharge 'devices' arevautomatioallyopened and Vvclosed when the closures of lthese openings are opened and closed. In thecase of ra'il.

` way ears a tank for storing air under pressure is supported beneath the car body which is kept charged with compressed air VAsupplied by al compressor operated either window are so arranged as to discharge at' an angle of 45 to thus produce air 4curtains` or shields outside the Windows. The pipes arerigidly attached to the jambe of the wmdows and the sashes are provided with tubes which iit over the perforated pipes and serve as sleeve valves for opening and closair line 'indicatin 'air discharge devlces at ing the perforations, the arrangement being such that the air passage openings are opened and closedA to 'the same extent that the window openingsy are opened and closed by the sashes. -The doors of the car. are associated with'vertical pipes which are' 'slotted `or 'perforated .through which a1r 1s discharged in such manner as to form a curtaingor shield to prevent the entrance of dust,insects, etc., to the cai-'and to `withdraw foul air therefrom. ,I' also preferably equip the car with devices arranged in the upper part of the car and aiso in other places to supply cool air tothe car. My improvements are illustratedhin the accompanyingdrawings, in which l Figure 1 1s a pers ective view of a raillvvayhcar equipped wit my im rovements.

otherstructures.` A'v conventional type of railway f'coach is indicated atl A, the windovsbeing illustrated at B, and a car door at A compressor may be. operated from the car axle as indicatedin Figure tric 'motor indicate Figure 2 at F.:

The tanlr D may be provided with a saiety valve as indicated. at G. The air line in dicated diagrainniatically in Figure 2.

I preferably, though not necessarily, em-

ploy a second -tanh I-I to 'which air is conf veyed by a pipe 71. from the tank D. This tank II may be cooled in any suitable way asy by iceintroduced through an opening closed by cover 1.7i. The pipe li may be con-i'` nected. with a cooling coil II which is in turn connected. with a pipe k, equipped with a gage Fu and :in air pressure regulator K.

M to the devices for'producing air curtains at the windows.

Each of these devices P comprises a bottom part p and two perforated vertical pipes p. The pipes p are secured to the window frames outside the window sash in the manner shown. Each sash B has' secured to it two tubes Q which serve as valves for opening and closing the Y perforations or openings in the pipes p.

These sleeve valves Q, are rigidly secured to the sash B and move upwardly and downwardly therewith. qWhen the sash is in its lowermost position all of the perforations or openings in the pipes p are closed and no air is drawn :trom the ipe system. When the sash is raised as indicated in Figure 5 the sleeve valves Q uncover the openings in the pipes p.and air escapes therefrom in the manner indicated. It is importantto observe that the perforations or openings in the pipes p are uncovered proportionately to the distance the sash is raised. Ii the sash is raised half way, only the perforations in the lower parts of the pipes p are un covered. If the sash is raised to its full extent, the perforations from' top to bottom of the pipes will be thus opened.` The pipes p are closed at their upper ends and when the sash B is closed no air escapes from the air supply pipes at the window where the closed sash is located.

In Figures 6 and 7 I have illustrated how my invention may be applied to an ordinary house window and it will be observed that the construction of the device is substantially the same and needs no further description. In this case, however, the supply pipe O is preferably provided with a valve o but the perioiationsor openings in the pipes 7i are in this case also'o ened and closed by means of sleeve valves It will be understood that each of the car windows is preferably .-Figure 3).

` assignee provided with thedeviees just: described aiiifl each of the car doors may be provided with-means for discharging air in such man vide a 'vertically arranged pipe It which connects with a ,pipe lit and entends along the inner edge' oi: Vthe door as indicatedin Fi gre 8. This pipe It is provided with per' iterations or slots i preferably arranged from to to bottom or the door. .it tubular casing surrounds the pipe It and this casing is attached to the door C by suitable devices T indicated iii-.Figure 6. The tubu lar casing S is providedwwith slots or' perforations s. .The arrangement is such that whenthe do'oris closed the .perforations e do not, register ,with the periorations r and air is-not discharged, but when the door is opened and the pertorations 1"' and a register or coincide; air will be discharged in the manner indicated in Figure 4. By the devices describedair shields or curtainsmay be provided attire openings in the car which not only Lsfe've to exclude foreign matter but which entrain air from theinside ot the car and cause foul air or impure airto be discharged therefrom whenever a window or door is opened. I preferably also provide means for introducing pure air to the car body and this is preferably done by the.

means particularly illustrated in Figures l and 2. For this purpose I provide a horizontally arranged pipe IlA in the top of the car which is connected by pipes V with the air pipes N. At suitable intervals along the pipes U I provide discharge roses or nozzles'W which are` perforated at w (see Each ofthese roses or nozzles is provided with a valve w by means of which any one of them may be cut oit when desired or they can be all opened for conjoint use whenever necessary. I have found that the passage of air through the openings Iw produces' a hissing noise unless some means is provided for preventing it and I have found that byV partially iilling the bulli with steel wool indicated at X this hissing noise is practically eliminated; at any rate very greatly reduced.'

My improvements were at iirst designed for use on railway cars, but I have since applied myimprovements to-the windows and doors of houses and other structures and so far as parts of my invention are concerned my improvements have a wide range of use.

I claim as my invention:

1. Ina ventilating system, the combination with a structure having awindow frame and upper and lower sashes mounted therein for vertical sliding movements, of vertically disposed tubes fixed to the lower portionsy of# the frame and on opposite sides thereof, said tubes being formed with lat erally disposedexit ports for directing air *ner as to prevent the. entrance o'finsects, cinders, dust, etc. For this purposel pro-iW il ll l (it) 2. In a Ventilating system, `the combina-l tion with a car body having a plurality of windows arranged along its sides and' 'including movable sashes, of va doorway lo cated at one end of the body, a movable door associated with said doorway, a source of compressed air, means for directing a portion of said compressedair into the body of the car, means for directing other portions of said compressed air to said windows and door whereby said air will be directed laterallyand outwardly across the windows and door when said windows and door are'in opened position, and means respectively associated with said windows and doorway for controlling the exit of said air upon vclosing movements of said window sashes and door.

In testimony whereof, I have hereunto subscribed my name.
